Remaining Filament Calculator

Basics

• This page goes over various ways to determine how much FDM Filament you have remaining on a Spool currently loaded into a printer
• It also covers the discussion of various devices that could automate this process

Existing Methods

• How Many Meters of Filament on a Spool + Length Printed (On the LCD Menu of a Printer)
  • And Meters of FDM Filament to Grams if need be
• This Calculator by "Deemoss" on their Thingiverse Page

Dedicated Hardware

• Put a Load Cell somewhere on a FDM Filament Spool Holder
• Thus you could mass the spool, enter what it should be, then it could measure both the length extruded and the lost mass
• Thus you would essentially have two methods of calculating it, and thus be able to accurately measure how much is left
